Let h^(2)(d^(2))be the hardy space over the bidisk d^(2),and let M_(φ)=[(z-φ(w))^(2)]be the submodule generated by(z-φ(w))^(2),whereφ(w)is a function in h∞(w).The related quotient module is denoted by N_(φ)=h^(2)(d^(2))ΘM_(φ).In the present paper,we study the Fredholmness of compression operators S_(z),S_(w) on N_(φ).whenφ(w)is a nonconstant inner function,we prove that the Beurling type theorem holds for the fringe operator F_(w) on[(z-w)^(2)]Θz[(z-w)^(2)]and the Beurling type theorem holds for the fringe operator Fz on M_(φ)ΘwM_(φ)ifφ(0)=***,we study some properties of F_(w) on[(z-w^(2))^(2)]Θz[(z-w^(2))^(2)].

The water Cherenkov detector Array(wCdA) is a major component of the Large high Altitude Air Sh.w.r Array Observatory(LhAASO), a new generation cosmic-ray experiment with unprecedented sensitivity, currently under construction. wCdA is aimed at the study of TeV γ-rays. In order to evaluate the prospects of searching for TeV γ-ray sources with.w.dA, we present a projection of the one-year sensitivity of wCdA to TeV γ-ray sources from TeVCat using an all-sky approach. Out of 128 TeVCat sources observable by wCdA up to a zenith angle of 45°, we estimate that 42 would be detectable in one year of observations at a median energy of 1 TeV. Most of them are Galactic sources, and the extragalactic sources are Active Galactic Nuclei(AGN).
